To It whom it may concern:

Be it known that I, LoUIs QUANOHI, a citizen of the United States, residing at Yonkers, in

. provements in Machines for Making Matrix- Blanks, of which the following is a full, clear, and exact Specification.

This invention relates to machines for making matrix-blanks, and has for its objects to provide a machine for making in one operation a matrix-blank composed of any desired number of sheets pasted and pressed together.

In the art to which this machine relates it is ordinarily the custom, so far as I am aware, to build up the matrix-blanks by hand, commencing with the back and pasting thereto by hand as many additional sheets as may be deslrec.

According to this invention I have provided a machine adapted to hold the requisite number of rolls of papers and operating to paste as many sheets together as may be necessary to form the matrix-blank.

The invention also comprehends novel pasting mechanism and various other improvements, all of which will be more fully described in connection with the accompanying drawings, and pointed out in the claims.

Referring to the drawings, Figure l is a side elevation of a machine embodying my invention. Fig. 2 is a similar view seen from the opposite side, showing the driving connections. Fig. 3 is a detail view of the adjustable side guide and paste-retainer. Fig. 4 is a detail of a side guide and paste-retainer for a constant width of sheet. Fig. 5 is a side view of a modification. Fig. 6 is a similar view seen from the opposite side; and Fig. 7 is a detail of one of the rollers, showing the attaching devices.

1 indicates the side frame of the machine, rigidly connected by cross-rods 2, upon which the operative parts are mounted. The machine is provided with as many pairs of rolls as there are webs to be pasted to form the matrix-blank, and I will now describe the form shown in Figs l and 2, which is adapted to form a matrix-blank composed of two or three webs. Matrix-blanks are ordinarily built up of one sheet of heavy paper, called the back, and several sheets of tissue paper, pasted and .pressed together, and I will describe the invention referring to the back in conjunction with the tissue, though it will be obvious that the invention is not to be confined to the use of webs of dissimilar thicknesses, since the various mechanisms can be independently adjusted according to the thickness and width of the webs to be pasted together. Mounted in trunnions 3 on the frame are supply-rollers 4 5 6, each having a spindle on which is mounted a tension-pulley 7 around which passes a tension-cord 8, fastened atone end and having its other end wound around stub-shafts 9, which can be turned and set by suitable setscrews 10 to vary the tension on the roller and prevent too rapid unwinding. Each of the supply-rollers is provided with suitable clips 11, Fig. 7, for holding the end of the web.

The pasting and pressing rollers are mounted in pairs and suitably geared together from the drivingshaft 12. 13 14 are pasting-rollers geared together by gears 15 16 and driven by gear 17 on driving-shaft 12. One of the rollers of each pair is mounted in eccentric bearings, as 18, in order to permit of an adjustment of the distance between them, this adjustment permitting the employment of webs of different thickness and also controlling the amount of paste applied to the web as it passes between the rolls. The other pair of pasterolls 2O 21 are similar to the rolls 13 14 and are driven in synchronism with rolls 13 14 from gear 16 through gears 22 23 24 25. 27 is a Winding-up roll which is driven from pulley 28 on shaft 12 through belt 29, and 30 is an adjustable idler for controlling the tension of driving-belt 29, so that as the diameter of the winding-up roll increases the web will not be pulled so hard as to break it, as would happen unless the belt could slip. 31 is the tension device for the rolls 27, similar to that above described for the supply-rolls. The roll 27 is mounted similarly to the supply-rolls, pivoted latches 32 being provided in all cases to hold the rolls in position while in operation. Mounted on the frame between the rolls 13 and 14: at opposite ends are adjustable edge guides and paste-retainers 33, each comprising a pointed portion 34, adapted to project between the rolls, and an angular slotted extension 35, which bears on the frame and is adjustable to follow the adjustment of the rolls and also transversely by means of a set-screw 72. It will be obvious that similar devices may be applied to the other rolls, and

it is my intention to so apply them in case the paper used in the machine is narrower than the rolls. In case one layer is narrow and the other wide I can adjust the guides 33 correspondingly. I have shown the rolls 2O 21 as providedwith triangular edge guides 38,. which have a shoulder 39, by which they are attached to the frame. As these guides are placed between the ends of the rollers and the frame they need not be adjustable; but in order to retain the paste they are set up closeto the ends of the rolls. In this space formed by the end guides and the rolls I place the paste, and by adjusting the rolls toward and from each other according to the thickness of the paper the amount of. paste applied to the web can be regulated. It will also be seen that the adjustable end guides can be set in for a narrow web, which can thus be pasted to a wide sheet running between the guides 38 without applying more paste than is necessary to cause the webs to adhere.

In Figs. 1 and 2 the course of the web is as follows: from supply-roller 4 over roller 14,

between it and roller 13, thence (in the case of three webs) down between rollers and 21 to winding-up roll 27. At the same time a web comes from supply-r0115, between rollers 20 and 21, and likewise from supply-roll 6. It will be seen that each web will have paste applied to the proper side to cause it to adhere to the other webs.

The machine shown in Figs. 1 and 2isadapted for work in small plants, where the desired number of plies can be built up by several successive operations. I also propose to use this machine for dampening and loading the supply-rolls. This is done by replacing one of the supply-rolls with a roll of paper as delivered from the manufacturer and suitably driving the supply-roll spindle, which for the time being is used as a winding-up roll. In winding the material for the back on the supply-roll it is dampened with a fine jet of water or steam from a perforated pipe 37, supplied in any well-known manner. To conveniently drive the supply-rolls 5 and 6, they may be set equidistantly from the pulley 28, so that the belt may be shifted from the winding-up roll 27 to either, as desired.

Referring now to Figs. 5 and 6, I show a machine for forming a matrix-blank of five plies. 4O 41 42 43 44 are supply-rolls carried in trunnions and provided with tension de-' vices, as before described. 45 is the windingup roll driven by belt 46 from the drivingpulley 47 connected to any suitable source of power. '48 49 50 51 52 53 54 55 are pairs of pasting and pressing rolls, corresponding, respectively, to the supply-rolls 40, 41, 42, 43, and 44. Each pair of pasting and pressing rolls is provided with end guides, as before described. Mounted on the shaft of drivingpulley 47 is a gear 56, which drives the pastingrollers through the train of gears 57 58 59 60 61 62 63 64 65 66 67 68 69 70 in a well-known manner. The pasting-rolls are adjustably mounted in eccentric bearings, as before described, in order to compensate for varying thicknesses of web and to regulate the amount of paste and pressure applied. Ordinarily in practice the back web will be on the roller 40 and will pass through the other rolls to receive the succeeding tissues. It will be seen that the back may have tissues applied to both sides, if desired, by suitably disposing the back relatively to the tissues. This form of the invention is intended for large plants where the full capacity of the machine can be used, and a dampener 71 may be located near the supply-roll for the back; but preferably the back is dampened when wound on the supply-roll and left for a time before being used.

In some instances matrix-blanks comprise more than one back in conjunction with the tissues, and such a matrix-blank may be made on this machine, as well as the ordinary one having a single back and one or more tissues.

, It will be understood that by the term paste used herein I mean to include, as well as the ordinary adhesive, various adhesive compositions, including that ordinarily used in making up matrix-blanks.

. It will be understood that I do not restrict myself to the precise construction I have .herein described, nor to any particular character of material used, as modifications and changes may be made without departing from the spirit of the invention.

Having thus described my invention, I declare that what I claim as new, and desire to secure by LettersPatent, is

1. In a machine for making matrix-blanks, the combination with a driving mechanism, and apair of rolls, one being eccentrioally mounted so as to be adjustable toward and from the other roll, of a flat angular plate carried by the frame and abutting against the ends of the rolls, whereby the rolls can be adjusted toward and from each other to vary the thickness without necessitating corresponding adjustment of the angular plate, substantially as described.

2. In a machine for making matrix-blanks, the combination with a plurality of supplyrolls, of a winding-up roll, pressing-rolls and a driving-shaft, the supply and winding-up rolls being belt-driven and located with respect to the driving-shaft so as to be alternatively driven thereby, by the same belt, a paste-receptacle formed by said pressing-rolls together with end plates carried by the frame and abutting closely against the ends of said rolls, substantially as described.
